Why your 3D tour dies on a buyer's phone

Product · Performance — 26 Aug 2026 — 6 min

A developer forwards us a competitor's interactive tour every few weeks, usually with a note saying it looked incredible in the demo. It probably did — on a laptop, on office Wi-Fi, for ninety seconds. That is not where it has to work.

Where it actually gets opened

Think about when someone genuinely looks at your development. Standing outside the hoarding. On the train home. In your sales gallery on venue Wi-Fi shared with forty other people. Forwarded to a spouse who opens it on a three-year-old phone with eight per cent battery.

None of those conditions resemble the demo you were shown.

The four failure modes

• It takes too long to appear. Every second before something meaningful is on screen costs you visitors, and the ones who leave are disproportionately on the weak connections — often the ones standing in your sales gallery.
• The picture is worse than your brochure. If your printed material looks better than your interactive tour, the tour is working against you.
• It gets slow after a minute or two. Phones throttle when they heat up. The frame rate falls away right around the point a serious buyer starts comparing apartments.
• It eats the battery. A buyer who watches their phone drop ten per cent while browsing your development closes the tab and does not come back.

The demo you are shown is the best case. Your buyer only ever sees the worst case.

Why this happens

Almost always because the tour makes the buyer's device do work it should never have been asked to do. Some tours push that work onto the phone directly. Others push it onto a server and stream the result, which trades the phone problem for a bandwidth problem and a cost that rises with every extra viewer.

Either way the buyer pays for it, in loading time, in image quality, or in battery.

The test that settles it

Do not evaluate a vendor from a demo they drive. Ask for a link and run this yourself. It takes four minutes and no technical knowledge:

• Open it on a mid-range phone, not your newest one.
• Turn Wi-Fi off and use mobile data.
• Time how long until you can see and select an apartment.
• Keep it open for three minutes and watch whether it stays smooth.
• Check the battery percentage before and after.

Any vendor confident in their product will hand you the link without hesitating. Ours is open at demo.orvala.io with sixty-six selectable apartments and no sign-up — run the same test on it and compare.

What to ask for in the contract

If the tour is going to carry your pre-sales, put a floor under it: a stated time-to-interactive on a mid-range device over mobile data, and a commitment that the sales-gallery build keeps working when the venue connection does not. Vendors who have solved this will agree to both. The ones who have not will explain why the question is unfair.
